## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ecb-key-policy-rates-2fab019e
```

Example prompt: What are the current ECB key policy rates — deposit facility, main refinancing, and marginal lending — and when did each one last change?

## When to prefer this

Choose this endpoint when you need the three canonical ECB benchmark rates in a single, structured call without parsing the ECB website yourself. Prefer it for finance, lending, treasury, or compliance workflows that require the current euro area monetary policy stance. Use the sibling ECB Data Portal time-series endpoint instead if you need historical rate series or custom ECB statistical data flows.

## Known failure modes

- Upstream ECB Data Portal unavailable — service may return a 5xx error
- Rate data temporarily stale if ECB portal has a publication delay
- Payment of 0.001 USDC required per call; missing or invalid payment returns 402
- No historical rates available — only the currently active rates are returned

## How this service works

Current ECB key interest rates: deposit facility rate, main refinancing operations rate and marginal lending facility rate, each with the date it took effect. Use it for euro interest rate context in finance, lending or treasury tasks. Note: free of charge at ecb.europa.eu; you pay for access, not for the data.

## Output

A JSON object containing the three current ECB key policy rates (deposit facility rate, main refinancing operations rate, marginal lending facility rate), each accompanied by the date on which it became effective.
